BRUNO IVESSELMANN, OF GUTTINGEN, GERMANY.

METAL-SHEARING MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,466, dated March 8,1898.

Application filed October '7, 1897.

To (LZZ whom it may concern:

Be it known that I, BRUNO "WEssnLMANN, a subject of the King of Prussia,Emperor of Germany, residing at Gottingen, 5a Friedlander Weg, in theProvince of Hanover, Kingdom of Prussia, Germany, have invented new anduseful Improvements in MetaLShearing Machines, of which the following isa specification.

The subject of the present invention is a metal-shearing machine inwhich the main surfaces of the blades do not lie in one and the sameplane, the blade in the lower shearin g-limb being set horizontally ornearly horizontally to the upper movable blade.

The invention further embraces the arrangement in the lower limb of twoblades, each having two cutting edges, said blades either lyingadjustably one upon the other or being fixed in a reversible limb orbearer, so that on using the shears, by simple turning of the bladeslying one upon the other or of the reversible limb or bearer, fourseparate cutting edges can be brought to work.

On the accompanying drawings the new shearing-machine is shownconstructed according to the methods above indicated.

Figure 1 is a front view, and Fig. 2 a plan view, of theshearing-machine having two blades lying one upon the other in the lowerlimb. Fig. 3 is a longitudinal section on the line a as, and Fig. 4. across-section on the line y y, Fig. 2. Fig. 5 shows a front View of theshearing-machine with reversible lower limb. Fig. 6 is a verticalsection on the line 2 a, Fig. 5; and Fig. 7 is a plan view.

a and a are the reversible lower shearingblades; b, the upper blade,moved by a lever in or other suitable means.

In the construction. shown in Figs. 1 to 4 the two horizontal blades aand aare so arranged one above the other that they may be adjustedrelatively to one another, and also by sliding in the lower limb crelatively to the movable blade. The fixing-screws d, Fig. 1, d 61,Figs. 2 to 4, of the blades for this purpose fit tightly in the blade a,while in the other blade a there is a slot (1 to receive thefixing-screws, this blade being therefore adjustable. 111 the under limb0 there is a slot (Z to receive each fixing-screw d or cl, so that bymeans of the set-screws f adjustment of Serial No. 654,444. (No model.)

and 7 the same object is attained by fixing the horizontal blades (6 ain a lower limb or carrier 0, which may be reversed in its posi' tion inthe framing of the shearing-machine. In this manner the four cuttingedges of the blades, without being themselves removed from their bed, bya reversal of the latter may be adjusted relatively to the upper bladeand be applied in shearing. In the machine here shown the framing isconstructed of two lateral standards 9 g, forming the bearings forlongitudinal bars It. On the two uppermost of these are centered theblade 11 and the downwardly-operating lever 70, while the two lower barsh carry the adjustable shearing-limb c. The reversal of the latter iseffected either by drawing it from the bars 7L (when the ends of theseat one side of the machine are free) or by taking the two halves of thelimb apart.

The arrangement just described,Figs. 5 to I 7, is especially adapted forcutting strips of particular breadth from metal plates, since the upperblade, together with the lever, and the lower blade with bed can beadjusted at will on the longitudinal bars according to the breadth ofthe metal strips to be cutthat is to say, the distance of the blades 19a from the right-hand standard g, which serves as abutment for the metalplate, can be adjusted to the breadth of strip required.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-- 1. A metal-shearing machine having theblades arranged at an angle to one another,

in which, for the purpose of bringing four cutting edges into operation,there are two blades resting one upon the other and adjustablerelatively to each other, so that according to the adjustment andreversal of the blades, each of the four cutting edges maybe broughtinto operation, all substantially as 3. A metal-shearing machine havingthe blades arranged at an angle to one another, 15 one of the bladesbeing composed of two plates or sections a and a reversiloly arranged,said plates or sections being loose or detachable from one another sothat each of said plates can have its edges set to the cutting line oredge, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

BRUNO WESSELMANN.
